We did a good amount of trees in the mid 2000's with fabric into CRP type ground. The conservation folks recommended not mowing or tilling along the rows, only to rely on the fabric. Well, it was a pretty big failure. Some made it but they are all stunted IMO. Really disappointed and wish we knew more then. I have guys swear that mowing a 5' strip on either side is just as good as tilling or spraying. I think I would go the mowing route with my next trees.
A question about the Junipers. Is there anything wrong with planting them? Some consider them invasive but they grow well on the prairie, you see them naturally in the Cheyenne River breaks, etc. But if you research some folks don't like them. I am thinking they would be a good, fast growing option for thermal cover. Maybe not 8 rows worth, but at least half or more. Thoughts?
